Rucksack.

p0001The invention relates to a rucksack according to the preamble of claim 1.

p0002Such a pack is known from DE-A 31 04 855th The frame of this backpack is divided into a frame upper part and a frame bottom part, which are each formed substantially U-shaped. The sides said frames are formed as interlocking movable telescopic tubes. Further, a fixing device is provided between the frame members, whereby the mutual distance between the frame parts is adjustable. On frame bottom part is arranged a support belt which comes on the sacral area of ​​the support to the support. The bag where the shoulder and hip straps are attached is fixed to the upper frame. By telescoping the frame parts is achieved that the support straps at the bottom of the frame base occupies a correct position for supporting against the sacral area. Since the shoulder and hip straps are attached to the bag, it is not possible to adjust the position of which the needs of the wearer.

p0003Another backpack is the US-A 40 15 759 can be removed. This frame includes a transverse member at which the upper ends of the shoulder straps are fastened. This crossmember is mounted adjustable in height on the frame. The lower ends of the shoulder strap are connected in the lower region with the frame. Between the frame and the hip belt an elastic, adjustable also in height joint is provided, which allows the wearer to lean your upper body over the hips.

p0004The US-A 41 94 656 shows a backpack frame, in which a mounting plate is provided for removably attaching the hip belt around the hips. The upper ends of the shoulder straps are mounted vertically adjustable on the frame.

p0005For the comfort in wearing it is crucial in a backpack, to adapt the frame to the anatomical conditions of the carrier. An important point here is a variability of the distance between the waist and the upper articulation points of the shoulder straps. However, this adjustment is not sufficient. Rather, continue to be important, the load on the carrier by the pack which is different depending on the weight and balance of the contents of the pack as well as the premises in which the wearer moves.

p0006When Backpack invention can be achieved by simple means an optimal wearing comfort reach. In this bag, it is possible to change the distance between the upper pivot points of the shoulder straps and the hip belt. It is also possible to attach the bag to the frame at different heights. On frame are packing bags of different sizes, ie different heights and thus different volumes fastened. The hip belt is fastened around a horizontal axis on the frame, so that the upper body of the wearer can be inclined without being obstructed by the frame laterally with respect to the waist of the wearer. The waist strap is easily detachable fixed to the frame so that it is possible to replace hip belts against each other without complicated installation.

p0007By the provision of the pack compression straps wrapped around it is possible to attach additional parts to the backpack, such as additional lateral panniers or ski rack.

p0008It is important that the means for height-adjustable mounting of the pack on the frame simultaneously serve, height adjustable to connect the two frame parts together.

p0009Embodiments are explained below with reference to the drawings. Show it:<ul><li>Fig. 1 is a view of a first embodiment of the frame;</li><li>Fig. 2 is a view of a second embodiment of the frame;</li><li>FIG. 3 is a plan view of a hip belt and</li><li>Fig. 4 is a side view of the backpack.</li></ul>

p0010The backpack frame 1 according to Fig. 1 consists of a frame top part 2 and a frame lower part 3. The frame upper part has two mutually parallel vertical side parts 4,5, which are interconnected by a transverse cross member 6. Similarly, the frame lower part 3 has two side parts 7,8, which are interconnected by a lower cross-beam. 9 The frame top part 2 and the frame lower part 3 are made of flat material in each case. The upper cross-member 6 has two oblong holes 10 on which the upper ends of the shoulder straps are fastened. The lower cross-beam 9 has a central bore 11 which intersects a horizontal slot.

p0011Along the side panels 4,5,7,8 are slot-shaped openings 12 provided by another of the same dimension in uniform intervals. The two lower openings 12 at the side parts 7,8 are used for fastening the lower ends of the shoulder straps.

p0012Over openings 12 at the upper ends of the side portions 7,8 and at the lower ends of the side parts 4,5, the frame parts are connected to each other 2.3. The connection between the frame parts 2,3 can be done so that the desired distance between the crossbars 6.9 results, which is adapted to the anatomical conditions of the wearer of the backpack. When connecting means are two cross-sectionally U-shaped angle iron with bolts and screw nuts. The bolts are guided through oblong holes 12 on the side parts 4,5,7,8 and are thus screwed together with the frame parts 2,3.

p0013Depending on the choice of the long holes 12 on the side panels 4,5,7,8 through which the bolts 14 of the angle iron are out 13, to provide the desired spacing between the transverse members 6.9.

p0014The slots 12 serve to continue the attachment of a bag pack on the rack 1, as described in detail later with reference to FIG. 4 will be explained.

p0015In the embodiment of FIG. 1, the frame parts 2,3 each H-shaped. In the embodiment of Fig. 2, the frame bottom part has three side parts 7,8, which are elongated in comparison with those of FIG. 1 upwards. In this embodiment, the frame upper part consists only of the cross-beam 6, which with the side parts 7,8 is vertically adjustable connected. The cross-beam 6 has at its two ends in each case a slot 15, corresponding to the slots 12 on the side parts 7,8. By means of these slots 15 is the cross-beam 6, each having a long hole 12 of the side parts 7,8 connected, which is likewise carried out by means of two angle irons 13, this time L-shaped cross section, and bolts 14 with screw nuts. In this way the crosspiece 6 can be attached to the frame part 3 at the desired distance from the transverse member. 9

p0016The hip belt 16 has a cup-shaped rear part 17, for example made of plastic. At this bowl-shaped rear portion 17 the loops 18,19 of the hip belt 16 are fixed. At the back part 17, a bolt 20 is mounted, projecting to the rear and to which is secured a vertically extending pin 21st When the waist belt 16 rotated 90 ° from its position of use and the pin 20 inserted into the bore 11, the pin 21 with the local slot is aligned, the waist belt 16 is secured by a rotation of 90 ° to the cross-beam. 9 In the position of use it is then compared to the frame 1 for rotation about the axis of the bolt 20, allowing the above-mentioned possibility of pivoting torso of the wearer without interference from the frame.

p0017On shell-shaped rear portion 17, a network 22 is chordal excited that enters the institution to bear against the sacrum. This network 22 ensures a distance between the sacrum and the rear part 17 and thereby reduces perspiration in this area.

p0018The attachment of the pack 23 on the frame 1 via the bag 23 arranged loops 24, which are guided by long holes 12 on the side panels 4,5,7,8 and each having an unillustrated buckle for securing the loop ends. In this manner, packing bags 23 different sizes at different heights on the frame 1 to be releasably secured. For fixing continue to serve two compression straps 25, which are also guided by long holes 12 and wrap around each of which the pack 23rd The two mutually vertically spaced extending compression straps 25 are lashed to the pack 23rd In them can be fastened for example, a side pocket 26 or mounts for attaching skis.

p0019At the wearer facing side of the pack 23 horizontally extending labels may be attached which, when aligned with the upper crossbeam 6, the securing of the pack 23 on the frame 1 at various altitudes easier. The loops 24 have a mutual distance corresponding to a multiple of the pitch arrangement of the elongated holes 12th
